To all wwm it may concern:

Be it known that I, CHARLES H. CLARK, a resident of Crafton, in the county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements in Tilting Side-Dump Cars, of which the following is aspecification.

This invention relatesto lthat class of dump cars in which the car body is inclined for discharging the load, and it contemplates a rocker mounting for the body of improved construction, the arrangement being such that during the tilting movement of the body the center of gravity of the combined body and load lowers, while the center of gravity of the body alone rises,

the result thatthe movement to inclined position is facilitated, and after the load has been discharged the tendency of the raised center of gravity of the body to lower causesA the body to move with ease back to normal position and remain therein.

A further purpose is to provide improved means for controlling and limiting the tilting movement.

AA further characteristic of the invention is the arrangement of the side walls of the car body, withmeans operating automatically to open the wall outwardly and downwardly at the emptying side of the ear. A

' further characteristic of the automatically opening side wall is that it forms a chutelike extension which directs the outflowing material fartheraway from the tracky than if it'were tofall directly from the inclined bottom of the car.

Still a further object is to provide improved cylinder and piston 'means for rocking the car body, together with improved detachable connections between the body and the pistons, whereby either of the cylinders may be rendered inoperative while the body is being rocked by the other cylinder.

The invention also includes features of novelty in the construction of the underrame, and in the rocker holsters which support the body.

lIn the accompanying drawings, `Figure 1 illustrates the improved car, one-half thereof being shown in side elevation and the other halt` in vertical section. one-halfv of the car is shown in. top plan, andthe other half on a plane beneath the rocking car body. In Fig. 3, one-half of the car is shown in end elevation and the other half in sectional elevation at' the bolster.

In Fig. 2

`irAzanns H. CLARK; or citAFToN,1=ENNsYIi.vANIA, AlssiGNoB To cLAaz cn'coM- Fig. 4 is a sectional elevation taken on line 4--4 of .Fig.`1, the body being shown in nor-` mal position in full lines and tilted, as 4when dumping, in dotted lines.

Referring to the drawings, the under-i frame consistsof the central lon itudinal girders 2 through which the draft orces'arev transmit-ted, 4and the' holsters 3 connecting the girders'2 coincident with center bearings 4. Girders 2 are covered for a portion of their length by plates Mounted on each of holsters 3 is thetransverse horizontal rack 6, and operative tliereon is the toothed rocker 7 ofthe body bolster 8.

As here constructed, the car-body, carried by bolsters 8, consists of the Longitudinal` center and side-floor girders 9 and 10, 11 being the floor or bottom, 12the end walls, and 13 longitudinal side walls. Trunnions 14 are projected from endfiivalls 12 at the center about which the body' turns when tipping,

the trunnions moving a horizontal line during such lmovement beneath the flanged or overhanging upper end`15 of the yokelike frames 16 raised from the ends of the car underframe.- These frames 16` provide v stops for the trunnions when the body reaches the limit of its tilting movement land prevent the same from becoming displaced.

. The body is rocked girders 2 by hangers 18, the cylinders being tied together by bars 19. The piston rod 20 of each cylinder carries at its upper end the horizontally turning clevis 21, the up.- wardly disposed arms of which are formed with the reversely facing hooks 22 adapted, when theclevis is turned, to engage or disengage bolt 23 at the lower end of the straps 24, depending from the under side of the body. Clevis 21 may be providedv with a pivoted handle or arm 24. which may be turned upward from, the position indicated in Fig. 4 for turning the clevis as required.

Cylinders 17 are connected to and operated by compressed air secured from the airbrake equipment or otherwise, but such connections are-not shown as they Aare old in the art, and no novelty is claimed for them.

The body is tilted or rocked by operating the cylinder on the side upon which the body is to lower,"the air under pressure'being admitted to the upper end of the cylinder, with .the lower end of the latter open to an exhaust, as will be understood. But before by means of two cylinders 17 suspended on opposite sides ofv which are hinged at 25 beneath the floor of the body, and coincident with these hinged arms are like downwardly extending arms 26. Thelatter are connected by links 27 to the extremities of the transverse floating beam or bar 28. As many of these connections between the opposite walls may be provided as required, four being here shown. Each of bars 28 operates between the slightly separated portions of a cradle-like bracket 29 supported by girders 2. The cradles have their inner faces or edges 30 curved downwardly 'to a central point, and adapted to travel on these curved' faces are rollers 31 on opposite sides at the center of bar 28. Said bar rests on rollers 32 at the base of the cradle and is always in engagement with at least one of these rollers. When the car body begins to tip, forinstance as in Fig. 4

with the 'left-hand side lowering, such movement, irrespective of pressure on side wall 13, imparts longitudinal movement to bar 28 toward the opposite side of the car, and at the same time causes roller 31 to ride upwardly on the curved face 30 of cradle 29, asin dotted lines in Fig. 4, this movement swinging side wall 13 outward and downward, at the same, time holding wall 13 on the opposite side in upright or closed position. When fully tipped, the body and its open side wall are 'in thel position indicated in dotted lines of Fig. 4, at which time the open and extended wall forms a chute-like extension for diverting the emptying load away from the track.

It is characteristic of the invention that the center of gravity of the loaded bodyl that as the car rocks to tiltingl position thesteps on the emptying side are drawn inward and out of the way.
